RandomThe random class in Java generates a pseudo-random number, uses the seed of 48-bit, and then calls a linear congruential formula linear congruence equation (Donald Knuth's programming Art of 3.2.1)If two random instances use the same seed, and
In the previous blog, we learned about the real random number generator based on physical phenomena, however, the real random number generation is slow, for the actual computation needs, the random number in the computer is generated by the program
RandomReproduced content, there are changes, thanks to the original author ()The random class in Java generates a pseudo-random number, uses the seed of 48-bit, and then calls a linear congruential formula linear congruence equation (Donald Knuth's
Introduction to linear homogeneous random number generator:
The old LCG (linear congruential generator) represents the best and simplest pseudo-random number generator algorithm. The main reason is that it is easy to understand, easy to implement,

1. Random numbers are generated by the combination of generator and distributorGenerator generator: Can produce discrete and other possible distribution of numerical distribution distributions: Can map the generator generated uniform distribution
How to generate random numbers in C/s + +: The rand () function, the Srand () function, and the random (int number) function in the C language/c++ are used here. (1) If you want to generate random numbers without setting the range, you can just use
